Ohh... I haven't tested much with community lots. I did try to shove a ton of food stalls onto one before and found out the hard way that they don't populate and need vendors hired manually lol. Oh snap, just realized Bar type lot lets bubble tea counter be a bar :)
I think the limit is for one or two food vendors and 3 sales tables on community space lots. If you stick to the limits they work wonderfully. There's mods you can use if you want to have vendors show up for all the stalls you add to the lot.
Ah.. I'll have to try that out on the community lot then. :) I try to play the game mod free, so mods aren't an option for me.
