This is a CSV format, You can use the csv lib from the stdlib :

# parse with : and | as delimiters
str = "Menu: steak_and_egg | date: 0814 | who: Anita"
parsed = CSV.parse(str, ":", "|")
=> [["Menu", " steak_and_egg "], [" date", " 0814 "], [" who", " Anita"]]

# then, put the results in a hash
res = {}
parsed.each do |k, v|
res[k.strip] = v.strip
end
=> {"date"=>"0814", "who"=>"Anita", "Menu"=>"steak_and_egg"}

You can also use Enumerable#inject for putting in the Hash (or Hash::[] with 
some adaptations)
