Have you had a truly well-executed dish (entree, app, side, whatever) in the Greater Boston area that really surprised you, that it would even be worth going to the place, sitting at the bar, and just ordering that dish?
Especially a place not usually on the Chowhound radar.
Examples for me:
1. The grilled artichoke hearts appetizer at Houston's (the Boston one).
They are really smoky, well-charred, perfectly tender, with lots of lemon. Unbelievable. I would be willing to bring a couple of foodie friends there, order a cocktail, and a few plates of those.
2. Skirt steak tacos at Bonfire.
Yes, Bonfire suffers from the over-the-top Todd English mediocrity, but the skirt steak tacos are really something special. Well marinated, darkly charred (a theme!), with avocado crema, in a soft flour tortilla---perfect contrast of smoky, creamy, hot, cold...
3. Frites au Bercy at Les Zygomates.
Not a huge fan of Les Zyg. BUT: These fries, served with gravy and a big, nasty knob of compound butter are a fat-addict's dream.
