Here are some quick reviews of places I've eaten in the past 2 days:
The Denver Chop House: On Wynkoop right next to Coors field. Great steak, great service, and a delicious raspberry lemonade cocktail that was out of this world. Spent ~$30 for a drink and entree.
Jamba Juice: On the corner of 16th and California, big yellow awning. Someone on this blog mentioned you could have one of their drinks for a meal. I happily did so and it was good to tide me over for a few hours. Being made of fruit, these drinks have a lot of sugar in them (most had 60 - 100 g), but there were a few "light" options that were under 60 grams. Spent $4 for a small (which was quite big).
Tokyo Joes: On the corner of 16th and Arapahoe. Great asian food where you could get sushi or choose from a number of noodle or rice bowls with different kinds of meats, veggies and sauces. Perfect portion sizes. Spent $9 for a drink and noodle bowl.
The Broker: On 17th between Stout and Ciampa. Located in the old bank vault of the Denver National Bank building, the atmosphere is pretty cool. Dinner was very pricey but all inclusive - shrimp bowl, salad or soup, entree, and dessert. OK, I splurged majorly on this one - spent ~$80 for filet mignon (with all previously mentioned courses) and one drink.
