Need serious last-minute first meeting/date advice!

I met a guy online and we're meeting tomorrow for dinner and drinks. Last night I found out it's his birthday the night of our date (he'll be 23) and that made me a uneasy/nervous since there's some kind of entertainment factor to live up to and I'm petrified of being boring or awkward.

I'm not 100% sure it could be called a date since we're not "dating", we're friends who have somewhat of an interest in each other but we're taking it slow. This makes me worry about how to act about certain things.

So if you have any first date tips like breaking the ice, keeping a conversation going, what to do at first contact (etc.) I'd be grateful to hear them. Thank you!
