I like to give restaurant gift certificates as wedding gifts, and I'm looking for relatively upscale, vegetarian-friendly ideas for a friend getting married in Chicago. They've been to Green Zebra a lot, so I'm looking for something different. One eats meat and one does not. Not super adventurous eaters, but they like a variety of ethnic foods. I'd like to spend $150-200 on a GC and know that that would cover most, if not all, of a nice meal. Many thanks!
