Thanks to all who've made suggestions and given so much thought to our party- I knew this would be the place to ask!
I've taken Gayle's suggestion (which was agreed upon by several others as well)- I went to Z's Fusion for lunch on Monday. It's across the street from the convention center, has a menu that I think will feed all the various tastes in our party (now 7), and I think that at dinner it will very much have the celebratory vibe we were desiring. Plus, a wine list with so many interesting choices under $40 can't be bad... and it's perhaps a $7 taxi from my house. How could we go wrong?
I'm going to call Limestone about adapting FMC to pescetarians... and if the answer is go, my husband and I will make our own special trip for two.
Thank you all again!
