I think beer gardens are classed as part of the pub. Just the street or a park or something is OK though I guess.

Nope. Outdoors at a pub is fine. Here's the guidance for Tier 2 (High):-

Visiting other venues, including shops, restaurants, pubs and places of worship

Venues following COVID-secure guidance can host more people in total, but no one must mix indoors with anyone who they do not live with (or have formed a support bubble with) unless exemptions apply. Outdoors, you can meet in groups of up to 6 people.

This includes in:

• pubs and restaurants
  
• shops
  
• leisure and entertainment venues
  
• places of worship
  
  

At least one person in your group should give their contact details to the venue or check in using the official NHS COVID-19 app so NHS Test and Trace can contact you if needed.
