Mint Cafe is my favorite Thai restaurant in Cleveland, hands down. Their noodle dishes are excellent, all of the ones I've tried -- especially the country-style pad thai, crazy noodles and jade noodles. The curries are superb as well, and my mother-in-law swears by the Tamarind Duck. Care is taken with presentation as well, and the food always looks beautiful. What's more, the prices are pretty affordable given how tasty and well-presented the food is.
We're pretty addicted to the bubble tea there, too; theirs is the best! Try the Thai iced tea flavored bubble tea.
