Abco:
In the original version in french the cost of the meal was 11 without denomination, so presumably Belgian Francs. In the later french versions this amount has never been changed.
Thanks for that info, Abco.

I don't know what BF 11 represented in 1938 and I can't find an "inflation calculator" site (nice stuff),capable of handling multiple currencies.
I haven't found a site which does historic conversions directly between Belgian francs and British pounds. But I
have just found this site -
www.measuringworth.com - which gives historic exchange rates between any currency and the US dollar. From this, I can obviously work out the Belgian franc to British pound exchange rate.
So here goes:
In 1938, 1 dollar equalled about 6 Belgian francs, and 1 dollar also equalled 0.2 British pounds.
So if 6 Belgian francs equalled 0.2 British pounds,
11 Belgian francs - the cost of Tintin's meal - would equal 0.36 British pounds.
Since there were 20 shillings to a pound, and twelve pence in a shilling, I think that 5 shillings and sixpence was about 0.28 of a pound (not that anyone back then was in the habit of expressing imperial money in such a decimal form!)
0.28 pounds would be about 9 and a half Belgian Francs in 1938, so that's not too far out from the 11 francs in Hergé's original. Given that the exchange rate must have fluctuated an bit throughout 1938 anyway, I think it's close enough to suggest that the English translators were giving a fair approximation of Hergé's 1938 meal price.
Whereas if I run the figures through for 1958, it doesn't even vaguely match up, since the Belgian franc exchange rate against the dollar and pound changed massively in post-war years. (I think this happened with a lot of European currencies immediately WW2 as part of post war reconstruction - the US Marshall Plan, the Bretton Woods Conference and the establishment of the IMF - but my history's a bit vague on that!)
Anyway, in 1958, 1 dollar equalled about
50 Belgian francs. As 1 dollar also equalled 0.35 British pounds (a much less drastic change), this means that 1 Belgian franc equals only 0.007 pounds! So our 11 Belgian franc figure equals only 0.077 pounds - way too cheap for a meal even back in the 1950s. Post-war French and Belgian readers must have read that 11 franc figure as a historic pre-war price.
So my guess is that the English translators were basing their 5 shillings and sixpence price roughly on Hergé's 1938 11 Belgian franc price, rather than going on the value of 11 Belgian francs in 1958.
But I'd also guess that 5 shillings and sixpence must also have sounded a plausible price for a meal for the 1958 readers of the first English edition, since they wouldn't have been assuming that British readers new to Tintin would realise it was set in the late 1930s.
