I thought the Mellow Mushroom's food was good, but the service had to be the worst in Ft Worth....
Joe T's was a horrible Idea for as many people as we had the last time. I know I heard many complaints from the table......

Truth is, many places will have problems providing good service with such a big party. I think Mellow Mushroom's service was bad for some, and good for others that night. Eat inside at a table for 6, and it's fine. But I digress...
I think Joe T's was just an unfortunate event due to the incliment weather. Had we been out on the patio, I think service would have been a little better for such a large party.
Bottom line is - there's only going to be a handful of places (IMHO) that can provide good service for a party of 20+. Those types of places already have rooms and wait-staff equipped for dealing with that. Generally, places prepared for large parties cost a little more - that's my experience. The other alternative, is going somewhere that it's serve yourself, such as Hard 8's or anyplace without a wait staff. I just think that with big parties, you have to expect less than "usual" service. However, I completely disagree with any establishment that automatically adds on gratuity for large parties and then proceeds to provide shotty service.

So.... my vote goes for McDonalds. It's serve yourself and they have a playground!
