This place is known for its amazing Saturday and Sunday dim sum brunches, in which customers choose from authentic comestibles presented on rolling carts. And it is precisely this movable feast that makes Tropical a great venue for a debut date. For one thing, you can order as much or as little as you want, which means the date can last as long or short as you wish. Like her? Slowly sample all 56 dumplings, buns, rolls, and tarts. Less than thrilled with him? Over shrimp rice pasta, develop a sudden seafood allergy. Want to test his spirit of adventure? Grab an order of chicken feet or fried squid heads. Need to know if she's got a gag reflex? Serve her a sample of congee garnished with a thousand-year-old egg. Best of all, whatever the outcome of this encounter, dim sum ends at 3:30 p.m., which means you've got the rest of the day to, uh, fool around.
