I called Colter's Grapevine and spoke to manager "Derek" to see if there would be any issues (like if they were closed or anything). I said expect maybe 24 people, we'd like to pull some tables together or be segregated if possible. They will give us their banquet room if it is not already booked, he was not sure, but as a minimum they'd pull some tables together.
Arrive around 10:30 as you prefer to socialize prior to entering the restaurant. They open at 11:00, we can go in anytime after that. I don't know what the parking lot looks like, so first Cobra's arriving, do what makes sense ...
If anyone gets lost you can reach me on my cell 214-738-4865. I won't be able to help you, but I'll tell everyone else you're gonna be late

Again, the address is:
1720 State Highway 26, Grapevine, TX .. adjacent to Bass Pro/Embassy Suites on the south, facing SR26 (Northwest Hwy).
and the map is attached about four messages back.
See you there!
