All of Sylva seems to have turned out tonight for cocktails and dinner at Restaurant 553. Diners have laid claim to the umbrella-shaded tables in the lush courtyard where hundreds of dahlias bloom. Well-dressed gentlemen are kicking back on the front porch of the 101-year-old cottage, enjoying microbrews and martinis. It’s no wonder this is a go-to spot for Lowcountry cuisine and more.
