I am not likely to be a BevMo customer. I buy better wine than they offer. However, I believe that the owners of Draeger's and Beltramo's are working purely out of self-interest by campaigning against BevMo.
The argument that BevMo would lower prices to the disadvantage of higher-price venues is unsavory, of course, and the threat (previously stated by Draeger's) that they would close the Menlo Park location is blackmail of the lowest sort (quite frankly, if they closed then maybe finally we could get our own Whole Foods).
In summary, I don't particularly think that BevMo would be a great addition to Menlo Park but I certainly do believe that an argument that prices would be lower and variety less to be wrong. I do see K&L Liquors in Redwood City thriving even though there is a BevMo within a few blocks of its location.
