Brussels's food section runs on 2 curated guides, restaurants and cafes, each holding 12 verified entries. The section treats these as 2 separate subjects. Each guide covers a different part of a Brussels day, and that separation is useful because the restaurants guide and the cafes guide answer genuinely different planning questions.
If your trip is built around evening meals, start with the restaurants guide. Open the cafes guide first if mornings matter more. Each holds 12 entries, enough to cover several days in Brussels without repeating anywhere. The 2 guides don't overlap, so reading both covers a full day.
August in Brussels averages 23 C with 12 rain days, warm enough for sidewalk tables but wet enough to rearrange an afternoon. September drops to 21 C with 11 rain days. The cafes guide tends to be the more practical one when a shower pushes plans indoors.
In August, Brussels sees 12 rain days against a 23 C average high, so the cafes guide doubles as a wet-weather fallback for any food plans.
