The Neptune Café and Bar is a community gathering spot for work and relaxation. The café is always filled with locals working remotely, planning trips, or friends catching up.

We have four rotating taps in-house featuring local beer and kombucha. We also serve wine, cider and have an array of teas, smoothies, juices and more. For the frugal and adventurous, we’ve even got a $2 tall boy can of PBR – for the dirtbag in all of us!

You’ll find all of your favorite café beverages including fresh coffee from local roaster Ampersand Coffee, espresso, herbal teas, yerba mate, chai teas and more.

Whether you need a quick snack or a full meal, the café has you covered. We cook up waffles, paninis and soups, and have pre-made salads and sandwiches ready around the clock. Have a sweet tooth? (Us too) We have a rotating selection of pastries, breads and cupcakes from local providers such as Spruce Confections and Kim & Jake’s Cakes.

We feel strongly about supporting local business, so you’ll see a variety of local brands in our Cafe. 

Stop by before or after a trip to Eldo or Boulder Canyon! See you here!
