Prague has extensive public transport options, including trams, buses and metro. One day travel pass costs around 4.5 EUR and a three-day pass costs around 12 EUR. Taxis and Uber are also widely available, but they can be more expensive.
If you have more time, consider visiting the Jewish Quarter, Petrin Hill or taking a river cruise. If you have less time, skip the beer tasting and visit the Old Jewish Cemetery instead.
