For pizza, we ordered the "Fritz's Favorite Topper" which includes sauerkraut and sausage. The toppings (all under the cheese) were plentiful. A dense medium pizza was way more than enough for two people. The cheese was all provolone (similar to Larosa's), which was not bad although a bit lacking in flavor... bordering on rubbery.
The crust was the killer for this pizza. It was sturdy enough to hold a lot of toppings, but with no air bubbles and little taste. It was also a much lighter color than typical. Possibly hinting at a pre-made frozen crust. It was just bad.
Pizza is pizza and so we ate it. But never again. Germantowne was a disappointment, not least because we were really hoping for it to be a great hidden gem. If you're craving pizza, we recommend heading down Madison Avenue for Giuseppe's (a very good pie) instead. For the bottom line on Germantown Pizza Haus, we defer to the great James Brown.
