Corvallis Brewpubs - Conclusions

Having visited and reviewed all four brewpubs here in Corvallis, I think I've reached some conclusions about their respective strengths and weaknesses. Here they are:

Old World Deli/Oregon Trail Brewing
Ambience: Acceptable, but the industrial chic motif is just too weird
Service: Non-existent
Food: Acceptable
Premise-brewed beer: Acceptable

McMennamins on Monroe
Ambience: Very good, striking interior and surprisingly quiet even when at/near capacity
Service: Good
Food: Not Acceptable
Premise-brewed beer: Acceptable

Block 15
Ambience: Good when at half-capacity, TOO LOUD when full
Service: Good
Food: Good
Premise-brewed beer: Very Good to Excellent

Flat Tail Brewing
Ambience: Good when at half-capacity, a bit loud when full (also the music can be turned up too high)
Service: Good
Food: Good
Premise-brewed beer: Acceptable

It doesn't take a statistical analysis to determine that Block 15 is the winner here, and it's certainly my personal choice. I just wish they could do something about the sound level.
