In an interesting form of protest, Marty Markowitz, Brooklyn’s Borough Prez, is threatening to — gasp — appear in a bathing suit in public unless Mayor Bloomberg reverses his decision to close the Gowanus “Double-D” public pool. Markowitz won’t be alone in his exhibitionism, as various city council members and other pro-poolers will be likewise suited.

The “Double-D” pool will take $200,000 to open, apparently. Is it worth it?

We’re just looking forward to all feeling better about our bathing-suit bods — seeing Markowitz in trunks is probably just as therapeutic as eating ice cream and watching The Biggest Loser.

Looking for a better way to cool down? We recommend Blue Marble, a purely Brooklyn ice-creamery with locations in Boerum Hill, Prospect Heights, and (newly) Cobble Hill. Plus, they added soft serve to their menu, at lease in some locations.

I’ve been spending a lot of time canoodling in Crown Heights these days — and despite the convenient Subway access and frequent drug busts, there was a time when I doubted I would ever be able to find a real restaurant (with waiters and everything) within walking distance.

Then I met Chavella’s.

Now, Chavella’s is actually in Prospect Heights, but still well within walking distance of my main squeeze’s CH pad. Anyway.

Chavella’s offers surprisingly authentic Mexican cuisine — the menu is full of spicy, succulent dishes, without a burrito in sight. Plus, it’s super-affordable: choose an inclusive brunch for $11.25, or à la carte options in the $3–$8 range. The drink menu is scant but satisfying, offering beer, sangria, red and white wine, and margaritas at times. (The Cinco de Mayo jalapeño margarita was a once in a lifetime experience — i.e., I wouldn’t try it again. It was delicious, but in a humbling, tongue-numbing sort of way.)

I recommend the tacos, which are $3 apiece, allowing for guilt-free experimenting, as well as the chiles rellenos con queso — the cheese-stuffed peppers that my Crown Heights amigo so enjoyed. But before you get to that stuff, be sure to order the guacamole app. It comes in an innocent looking animal-shaped bowl, but don’t be fooled — it will absolutely ruin guac for you anywhere else.

Brooklyn bound riders on the (2) and (4) trains will see modified late night service this week.

Between 12:01 a.m. and 5:00 a.m. between tonight and Friday morning, service on the (2) train will operate as express trains instead of locals between Atlantic Avenue, Prospect Heights, and Crown Heights-Utica Avenue, stopping only at Franklin Avenue Station.  Direct (2) train service to and from Manhattan and The Bronx will operate to Utica Avenue instead of Flatbush Avenue.  A (2) shuttle train with 30 minute headways will operate between Franklin Avenue and Flatbush Avenue…

Additionally, the (4) train will also operate express between Atlantic Avenue and Utica Avenue.

Brooklyn-bound passengers travelling from Manhattan and Downtown Brooklyn to Bergen Street, Grand Army Plaza, Eastern Parkway, Nostrand Avenue, and Kingston Avenue stations should get off the Brooklyn-bound trains at Utica Avenue, then board a Manhattan-bound train to reach these stations…

The late-night (G) train service adjustments reported by Brooklyn News last week remain in effect through the rest of this week.  This involves two sections of (G) service – one section will operate between Court Square, Queens, and Bedford-Nostrand, Bed-Stuy, the other between Bedford-Nostrand and Church Avenue, Kensington.  Trains will operate both sections every 30 minutes with passengers required to transfer at Bedford-Nostrand.  This will be in effect between 11:00 p.m. and 5:00 a.m…

Riders on the (L) train should be aware of platform boarding changes for late night service.  Brooklyn-bound riders will be required to board on the Manhattan-bound platforms at 3rd Avenue and 1st Avenue stations in Manhattan and at Bedford Avenue Station, Williamsburg, between 12:01 a.m. and 5:00 a.m. through Friday morning…

Manhattan- and Queens-bound riders on the (N) will see service re-routed over the Manhattan Bridge instead of the Montague Tunnel, skipping the Canal Street, Rector Street, and Whitehall Street stations in Manhattan and Court Street and Lawrence Street stations in Brooklyn.  Riders are asked to take the (4) train as an alternative…

And, finally, the (Q) train will be operating in two sections during late night hours.  The (Q) will operate in two sections – one segment will operate between 57th Street/7th Avenue, Manhattan and Atlantic Avenue/Pacific Avenue, Prospect Heights on the 4th Avenue Line (served by the (D), (M), (N), and (R) trains; the other section will operate between the Atlantic Avenue on the Brighton Line (the normal (Q) train station) and Coney Island-Stillwell Avenue.  Trains will operate every 30 minutes on the Brighton Line between 12:01 a.m. and 5:00 a.m. nightly through Friday.

This is in addition to the ongoing construction on the Brighton Line, causing intermittant delays on the (B) and (Q) trains and local service on the (B) between Prospect Park and Brighton Beach.
