Dunkin' - Castle Rock

Castle Rock's first Dunkin' is now open at 1185 Aloha Street in Founders Marketplace, daily from 5 a.m. to 7 p.m. Its grand opening celebration was held Saturday, Oct. 24, 2026, 8 to 10 a.m. Read our full story →

The first 100 guests in line got Free Coffee for 100 Days: a free medium hot or iced coffee in the Dunkin' Rewards app for 100 consecutive days, after entering the promo code they were given that day. The offer excludes Cold Brew, Nitro Cold Brew and espresso drinks, and it was open to Colorado residents in the Castle Rock area who are Dunkin' Rewards members; no purchase necessary. From 8 to 10 a.m. there were branded merchandise giveaways from a prize wheel and an appearance by Cuppy, Dunkin's mascot. At 9 a.m., Quality Brand Group hosted the official ribbon cutting, followed by a $3,000 check from Dunkin' and its Joy in Childhood Foundation to Children's Hospital Colorado.

It is built to Dunkin's Next Generation design, the format the chain has been rolling out nationally. Per Dunkin', the Castle Rock store has:

• A tap system for cold drinks — iced coffee, iced tea, Cold Brew, and Nitro-Infused Cold Brew, which is a Next Gen exclusive
• A dedicated mobile-order pickup area with a digital order status board, for orders placed ahead in the Dunkin' app
• A drive-thru, free Wi-Fi, and a front-facing bakery case

Curbside pickup: When we stopped by Oct. 21, two parking spots out front were marked for curbside pickup. Dunkin's app lets you order ahead, choose Curbside, and tap 'I'm Here' so staff bring the order out (per Dunkin's curbside guide).

The restaurant is just under 1,600 square feet and employs about 15 people. It is locally owned and operated by Quality Brand Group, a Dunkin' franchisee network, and is that group's 18th Dunkin' in Colorado.
