I'm late in posting this, as I'm currently traveling, but better late than never when it comes to restaurant deals- check out Dine In Brooklyn, the borough's answer to Restaurant Week, running from March 24th through March 31st! You already know the deal- 3 course prix fixe lunches and dinners for $23 at over 175 BK restaurants (though be sure to check the website to see which restos are doing dinner, lunch, or both), including Red Bamboo Vegetarian, Food 4 Thought Cafe, Smooch, and other veg-friendly places. Cuisines like Italian and Indian can easily be made vegetarian, so be sure to call and ask about substitutions!
Another cool foodie event to check out this weekend: the biannual James Beard Foundation Cookbook Sale this Saturday from 10am to 1pm at the James Beard House on W. 12th Street. With free admission and titles for as little as $5, take an hour and browse for some veg titles, or at least some books where you can do your own recipe adapting!
