My husband and I had afternoon tea at English's before a matinee at Town Square and loved it! It's not the Mandarin Oriental but $50 for a bottle of champagne, unlimited tea and as many cute little fancy tea snacks as you care to eat is a pretty fabulous deal. (The regular tea is $20/person so I don't know why you wouldn't want to add $10 for a bottle of champagne and some chocolate-covered strawberries!)
On a nice day like today, it is extremely pleasant to sit on their balcony and sip champagne and Earl Grey while looking out over the little park below. We had fresh hot scones with jam and cream, four kinds of little sandwiches (cucumber, smoked salmon, egg and cheddar/pickle) and an array of cute little desserts. The scones and desserts and accompaniments are made in-house and they are very yummy. And you can have as many as you want! We took seconds of the cheese/pickle and egg sandwiches and consumed three pots of tea (English breakfast, Earl Grey and jasmine) and had a perfect, leisurely lunch.
I'm a sucker for afternoon tea (it makes me feel all Downton Abbey) so we will be back for sure.
