I've been to sweet tomatoes for many many times and still love it very much. First, when I feel I need high-fiber dinner, I go! There are basically two zones of food (Salad vs. soup, desert, pasta). Everyone can take two plates on a tray every time (kinda hard to put everything I want in a plate :P). It's also a ALL-YOU-CAN-EAT restaurant. I love every vegetable&fruit there.
Second, when the weather is cold and I just want a bowl of hot soup, I go! More than 7 kinds of soups. The Big Chunk Chicken Noodle is the best, even though sometimes it might be too salty. chocolate/blueberry/coconut Muffins are all good. Baked sweet potato is bomb. Pizza and pasta are ok. I'm not a big fan of these choices.
Third, when you wanna SAVE $$, please go. There is no place healthier and cheaper than sweet tomatoes. I can have all nutrients I need in a day but absolutely yummy and healthy.
