Kati is a great Thai spot near Stuy Town. Appetizers are $4-6, entrees are $8-10 and if that alone doesn't convince you to go, buy a Restaurant(.)com certificate before you head out for even more savings. I typically only buy Restaurant(.)com certificates for 70-80% off, so I'll pay $2 for a $25 certificate with a min. food order of $35. That's an automatic savings of $23 when you spend more than $35. When I go with friends (2 friends is optimal for savings) we usually order two appetizers (highly recommend the calamari for $5 or vegetable dumplings for $4) and we each get an entree (I'm a huge fan of their chicken pad thai). Add that up, minus our cert. and we're looking at $10-15...TOTAL (plus tax and tip). For that price there's no reason NOT to try it...and it's good to boot!
Pros: Low prices, calamari, chicken pad thai
