Denver travel tips

1) Do not forget about hydrating when drinking alcohol in Denver

Bear in mind that Denver is located 1.5 kilometres above sea level. If you want to explore spirits in this city, be sure to hydrate and pace yourself since alcohol has a greater effect due to the height.

2) Experience the concept of “no goods over $100” in Denver

The fact about the expensiveness of qualitative clothes turns into a myth at Inspyre Boutique in Denver. Their aim is to provide visitors with high-quality clothes and accessories while keeping everything under $100. The choice is wide so you are likely to find something matching your taste and budget.

3) Indulge your inner gourmet at Rioja in Denver

All local gourmets of Denver gather at Rioja restaurant on 1431 Larimer Street. The main reason for this is an innovative and modern cuisine. For around $40 you will get a main course (like foie gras mousse), some snacks (like a cheese plate) and desserts.
