"Baker Miller, a bakery and cafe in Lincoln Square, continues indoor dining but requires diners to show proof of having a booster shot, in addition to the two initial rounds of vaccination (or one round for Johnson & Johnson). Owners Dave and Megan Miller made this decision to ensure safety during their busiest season, despite losing some business due to earlier vaccination proof requirements. The decision was influenced by studies indicating booster shots increase antibodies against the virus." - aimee.levitt
