Dinner across Fort Worth: DiMassi's

This is an open, spacious Mediterranean buffet: all-you-can-eat for about $25.
They don't serve liquor and you can't BYOB - but we can do that at some other event before long.
The attendance limit is 20.
They don't take reservations but they are almost never crowded, so we'll put the tables together on arrival.
You can RSVP until 5 PM the day of the event.
