I found this (see link) when I googled "bar height trestle table". The one you have pictured looks like it could be custom made. I don't know about your area, but in my area, there are a few that advertise on Craigslist that make similar style furniture.

Looks like a metal top? If you can't find it, look for a trestle table and wrap the top with zinc sheet metal.

I started out looking for a counter height trestle table. There are some that are similar.

Here's a different trestle style

Another one sold as a set

Another set

And another set

Not seeing your exact table, but similar ones. Most counter or pub height tables are plain squares or rectangles -- not very interesting. I remember seeing some trestle tables on custommade (.com) and inquired about having one made as a counter height. I also looked at some Amish table that could be done at counter height. In the end, I found someone local who does amazing tables, so I ordered from him, but there are a a lot of options out there.

BTW, a counter eight table is 36" high -- about 6 inches higher than dining height tables. A bar heigth would generally be 42" high -- a full foot taller than a dining table. Bar tables will tend to be smaller and square or round. Pub can refer to either, so make sure you're looking for the height you want.
