I visit the original Walnut Cafe (on 30th) several times each year when traveling through Boulder. Last weekend was perfect for an early breakfast outside, so off to the Walnut. I entered the restaurant to be seated, per the sign, and was flagrantly ignored by two employees having a conversation over the cash register. One finally noticed me and I was seated outside. The meal was delicious, as usual, in spite of the uninspired service. My coffee drink (a cappuccino) was finally delivered around the time I finished the large breakfast, with not even an apology to acknowledge the long delay.
Very disappointing overall. I felt taken for granted as I handed over my money (and left a tip). The laid back approach to restaurant management can be taken too far, as seemed to occur in this case.
