Matt's is good and certainly worth doing at least once. The food is solid to above average even if it is a little pricey for breakfast but not outrageous.
The real draw is the location which is next to the downtown farmers market. So on Saturday you can hit the market while waiting for your table, buy something to strengthen your locavore cred and then eat at Matt's which is a hip reclaimed location.
Then off to buy some new Steampunk junk..
