Loge, Mezz, Grand Circle, Dress Circle, Balcony?

I'm shopping for tickets in the West End I'm seeing some terms that, to be frank, are used in the US too but I never quite understood (basically how the "circle" ones fit into the scheme)

Which of these terms are lower or higher and are some only appropriate in theaters with two balconies?
Loge, Mezzanine, Dress Circle, Grand Circle and Balcony?
(I'm fine with calling orchestra seats "stalls" - although it does seem a bit horsey.)

Some theatres have different names for the various Circles though so it's always bets to check the seating chart. Check out http://www.theatremonkey.com/. It's a great resource for all West End theatres."

Thanks!

So in general, If I'm correct
- Dress Circle is what is referred to as "Front Mezz" (or less commonly Loge) around here, (basically the front section of the first balcony, usually in front of a transverse aisle.
- Upper Circle is basically "Rear Mezz" (the space behind the transverse aisle)
- Balcony is most commonly the second balcony

I'll check out theatremonkey! I've been trying for a month to join theatreforum and keep getting timeouts on their side so I can't post or read discussions. (I've tried different browsers, devices, internet providers and hard-coded DNS - still times out on a proxy server of some sort on their side)
