<human>: After a little over a year, my ex and I broke up. It's been 5 or so weeks since and my cousin wanted to set me up with one of her coworkers so I figured what the hell, I'll give it a shot. After looking him up on Facebook, I had determined it wouldn't be a match but agreed to get coffee anyways. We met up at the coffee shop a few days ago and wound up talking for almost 4 hours. It was incredible and I misjudged him. 

At the end of our coffee date, he asked me if he could take me to dinner this week to which I said yes. Today he told me where we were going and it turns out to be a restaurant that my ex's best friend works as a waiter at. I don't want to come off as a bitch by "flaunting" my new date in front of my ex's best friend (who I got along really well with also) but I also don't want to give my date the wrong impression and make him question whether he should be on the date with me.

So I guess, is it weird if I message the guy who works at the restaurant to give him a heads up I'll be going or should I tell my date or what? I don't know how to handle this situation because it's a really nice restaurant and I'd love to go out with this guy, but don't want to ruin it.

Give me the gist of the text in a nutshell
<bot>: guy wants to take me on a date to a restaurant where my ex's best friend works as a waiter. Should we go somewhere else or what?
