Location, location, location!
Lost Dutchman Coffee House gets business not because it has great service or amazing drinks. Customers come because it is the closest coffee shop to many of the city buildings and has a small parking lot out front (a luxury most Main Street businesses do not have). I guess those two things translates into not needing to care as much.
It is very hit but more miss with this place. Drinks are pricey for what you get and the staff has an attitude more often then not. Also, the bathroom has an odd smell to it...
There are ALOT of other coffee shops in Downtown Mesa that do it better. I suggest going to one of them instead but if you have a caffeine emergency Lost Dutchman will do.
