I went there last night (after finding Irena closed) with the bf. I was very underwhelmed by both the service and the food (so correspondingly overwhelmed by the prices). Nothing was "bad", but nothing was "good" either (not much flavor). We had:
* Mozzarella w/Tomatoes - good and fresh, but a little heavy on the pesto
* New Zealand Lamb - good lamb but it had a strange flavor to it, came with rice and broccoli, both unnotable
* Linguine with Clams - pasta seemed mushy but undercooked (how is that possible?), way too watery, most of the clams were empty but the ones that weren't were delicious
For the price, I would definitely not recommend the Red House in Cambridge.
