Caldero 7.8
Cow Hollow
A cozy Spanish goods boutique that hosts paella, tapas, and wine tastings on Union Street. It’s a casual, intimate way to share tortilla, gambas, and a glass of Spanish wine without the formality of a full restaurant.
Must-Try Dishes: Seafood Paella, Tortilla Española, Gambas al Ajillo

Value: 8 Service: 7.8 Consistency: 7.2 Food Quality: 8.2 Atmosphere: 7.1 Cultural Relevance: 7.6
What makes it special: Spanish market with evening tastings and tapas-driven events.
Who should go: Couples who enjoy casual wine-and-tapas nights
When to visit: Check event nights; weekend early evening is ideal
What to order: Seafood paella, tortilla española, gambas al ajillo
Insider tip: Follow their schedule for pop-up tastings; limited counter space fills fast.
Logistics & Planning
Parking: Street parking on Union Street can be limited, but nearby residential blocks typically have open spots after 7pm; no valet service offered.
Dress code: Smart casual — jeans and a nice top are fine, but many guests lean semi-dressy for evening tastings.
Noise level: Moderate — conversation is comfortable during tastings, though background chatter rises at peak hours.
Weekend wait: Arrive early or book tasting slots; walk-ins after 7pm may wait 30–45 minutes for counter space.
Weekday lunch: No wait typically; events begin later in the day.
Dietary Options
Vegetarian options: Yes — tortilla española, patatas bravas, and manchego plates are reliable choices.
Vegan options: Limited — 2–3 small plates can be adapted on request, such as grilled vegetables and olive-based tapas.
Gluten-free options: Yes — many tapas are naturally gluten-free; staff can guide safe options for paella and proteins.
Good to Know
Is this good for a first date? Yes — it’s low-pressure, cozy, and offers easy conversation flow over shared tapas and wine flights.
Can I get a table without a reservation? Sometimes — small counter space fills quickly on event nights, but early arrivals (before 6:30pm) can usually be accommodated.
Is it kid-friendly? Not ideal — it’s designed for adults enjoying wine and tapas; better suited for couples or small friend groups.
Best For
Better for: Casual, intimate Spanish wine nights with boutique-market charm rather than full-service dining.
Skip if: You’re seeking a full dinner experience or extensive seating — opt for a traditional Spanish restaurant instead.
