We went for 5280 week. This was our first time at Cafe Prague, although we've tried to go for a while off and on. They do not have an account with Open Table (but they SHOULD), so to get reservations (which are almost a must), you have to call during dinner hours. They are pretty busy all the time, mostly with an older crowd (50 and over mostly). Not that an older crowd is bad, it is just a different dynamic.
We were seated right away, and service throughout was very good. We thought the 5280 menu was very good and thought it was a very good value, including a $26.40 (half of 5280) bottle of wine. Our broccoli soup, caesar salad, orange pepper duck and pork entrees, bread, and crepe dessert were all good, and a few other items on the 5280 menu looked appealing as well. Overall, good service, good value for $52.80, and a good experience.
On a side note, when we looked at their main menu, almost every entree was over $25. We really feel that is way too high, as even the very best restaurants in the Denver area charge from $18-25 for their entrees (excluding absurd steakhouses). While Cafe Prague is good, it doesn't run with the big dogs, if you will.
You can find free parking in Morrison if you don't mind walking a block. If you must park across the street from the restaurants, it will cost you at the pay lot.
