how to open a restaurant featuring Pokemon

I don’t think so. There was a Pokemon-themed cafe I knew once, and it didn’t seem as if they collaborated with the Pokemon Co. Better ask the Pokemon Company to be sure though.
Are you planning on opening a Pokemon cafe?
 
I came across a small restaurant in Paris whose menus were named after the three Kanto starters (with one even being misspelled) & their pictures, but there didn't seem to be any official disclaimer/logo or anything to show a partnership.
But yeah as it's been said previously, I do not think that TPC will give any sort of permission unless you're a major company, and they prolly won't mind if you do it w/o permission because they will probably never know about it
 
I think it depends on the scale of the thing. If it's just a small cafe in some town, nobody's gonna care. If it turns into a huge chain and you expand everywhere and make huge profits, then yeah their lawyers will probably start contacting you.

It very much depends on the company though. Nintendo (and TPCi) are pretty lax about this, whereas others like Disney and Sanrio are ruthless at defending their IPs.

source: have made and have friends who make fan merchandise, where it's the same rough idea.
