1 part Beer (draught is preferred)
1 part 7-Up
3 Ice cubes
The beer is first. The 7-Up is second. The ice is last, but it is only needed if the other ingredients aren't cold.
The amount can be slightly more or less, depending on the drinker's preference. Women tend to prefer more 7-Up and men tend to prefer more beer when asked. BUT, half and half are the ususal measurements. -- This drink is very popular in most of Spain, but especially in Madrid. You order it if you really don't want to drink a lot. It's a very "social" drink. People not used to drinking find it very gentle. In Spain, 7-Up is known, but "gaseosa" is what's used in the drink.
