Help....want to enjoy tonight.

Okay so tonight I have to attend a big bash with friends.  We are meeting at a pub for supper and then doing the bar/pub crawl around town.  This will be an all night late night party.

So my questions is I need some advice on what to eat at the pub for supper and keep me full.  Plus any drink idea's with low calories instead of just light beer.  I know there will be lots of shooters anyone know a good one to stick too? 

I want to have drinks and celebrate and eat with my friends but I do want to try to be smart about it.

Thank you....

can you check online for the menu at the pub? That should let you check ahead of time. I don't know much about pub foods and drinks aren't my forte. Sorry.
