If you want to get together, you got to make it real simple:
Name of restaurant
Date
Time
What you want to do (special menu, order off the menu and share)
An approximate cost helps as some of us are on budgets
Do realize that no matter date or time, someone else will propose another day of the week as better for them. ***BUT*** the person who is contacting the restaurant and doing all the leg work gets to choose the time.
If you start changing the date around, that causes problems with the folks that have signed up already.
Sometimes you get 30 people, sometimes 5-6 people. Surprisingly, I have had more fun with the smaller groups.
