We bought the Inglesina Fast Table chair and have loved it. It folds flat and into a built in bag that stores in its back pocket. I got it at BBB with a 20% coupon.

I’ve had the ones where you strap to the chair and the type where you clip on to the table. I haven’t used the tall folding chair type. The strap to the chair option can be bulky compared to the clip on to the table, that’s the only drawback in my opinion, but it’s great because you can strap it to any kind of chair or just set it on the floor (if you’re having a picnic on the ground) or at a booth type table. For the clip on, it folds up so it’s portable and doesn’t take up much space, but sometimes the tables could be too thick or have some kind of border so you can’t clip it to the table, or if we’ve been at a friend’s house where the table is so nice, I have felt uncomfortable strapping the chair to it, or you can’t put it on the ground. Both cost around $25.

We love this one and at less than $14 it is cheap as well.

@tlcbaby: I have the Chicco one @LuLu Mom: linked to. I think it's just OK. There are a fair number of limitations to what kind of table it can be used on- no pedastal tables, only the kind with foru legs (could tip with the extra weight), nothing flimsy, and I have had problems with some tables that can expand with leaves in the middle-- the frame under the table can get in the way of the hook on part-- usually she had to sit at the head of the table in that case. And like @kakimochi: mentioned, sometimes I just don't feel comfortable hooking it to a really nice table at a friend's house. Other than those drawbacks, it's quick to set up, doesn't take up a lot of space, and goes right in the washing machine.

Mine was a hand me down and we have hardly used it-- at restaurants, we always use their high chairs, and half the time when we are visiting we can't use it with the table our hosts have.

I'm intrigued by this one: http://www.amazon.com/Ciao-Portable-Travel-Chair-Black/dp/B0072IINY8#
My friend has it and loves it, but it has its own set of drawbacks (baby can't sit at the table and would probably be lower than table height, for one, and it's pricey.)

We have two of the same as @sunny and they are awesome.
