Although Harry Morgan models itself on the Big Apple’s Jewish filling stations, the portions are distinctly less generous & the prices significantly higher than you’d find in New York’s Katz or Carnegie Deli. Nevertheless, for a taste of Jewish-grandma-style cooking, the menu ticks every box. Gefilte fish, chopped liver, potato latkes & chicken soup with kneidlach are all present, & the kitchen also does a popular line in breakfasts. Outdoor seating on St John’s Wood High Street is mobbed during the summer, but there’s a takeaway service for those who don’t have time to linger for a meal. Local workers on the hoof pop in at lunchtime & grab hot salt-beef sandwiches smeared with English mustard to go.
