Going to eat at the restaurant my ex still works at?

We dated a few years. And were on and off again throughout the past year.The last time we were dating he broke it off, but then a few months later called me and wanted to try again. I'm happy with my new boyfriend I told him and he was upset. We are still fb friends and he always is liking my pictures. So I don't think he's over it still. I love the restaurant he works at and I want to go so bad. Its the only fondue place around. I just don't want him to think I'm trying to drop in on him or make him jealous if me and my new boyfriend go. I don't want to upset him. Not to mention if he's mad about the break up what he might do to our food. I thought about maybe letting him know somehow. Just to tell him I don't mean anything by going so it's not a shock when he sees me. Shld I even go? Any input is appreciated.

i texted him when I would be there. he said he would make sure not to be there, but I should have fun. everyone recognized me and asked how I was. there was no drama and my boyfriend was fine :)
